findAssocs() is not working, as is seen below. "Lucid" and "dreaming" occur together quite often in the book.
The corpus is a single document, the text version of a book. Does this function require at least two documents? If so, if I split the book in half will I get the correlations regarding the book as a whole, or in regards to how the two halves compare to each other?
> docs <- tm_map(docs, stemDocument)
> dtm <- DocumentTermMatrix(docs)
> freq <- colSums(as.matrix(dtm))
> ord <- order(freq)
